GEAR ACTUATING AND LOCKING MECHANISM.

Application tiled October 12, 1917.

T all whom it may concern:

Be it known that l, Fnnnmuox J. Tono, a subject of the King of Great Britain residing in Egg Harbor, county of Atlantic, and State of New Jersey, have invented a new and useful Gear Actuating and Locking Mechanism, of which the following iS a specification.

My invention relates to means for operating and locking the gearing such as may be employed for regulating the position of a window member, such, for example, as employed in a vehicle, as an automobile, carriage or the like.

My invention resides in apparatus of the character referred to comprising a driving wheell or gear which is in turn driven by a pinion which is movable with respect to a locking member, whereby the pinion in oneV position is locked and locks the driving` wheel or gear, and in another position is freed from the locking means and is free to drive the driving wheel or gear; and for rotating the pinion and for moving it longitudinally I provide a suitable handle, preferably .in the form of a crank, which in movement to one position frees the pinion from the locking member and in movement to the other position causes or allows movement of the pinion to locking position.

My invention resides in structure of the character hereinafter described and pointed out in the claims. i

For an illustration Otis/ome of the forms my invention may take, reference is to be had to the accompanying drawings, in which:

Figure 1 is an elevational view of a window structure having applied thereto mechanism embodying my invention.

Fig. 2 is a vertical sectional view, on enlarged scale, of art of the window structure shown in Fig. 1 and of my improvedmechanism.

Fig. 3 is a fragmentary sectional view showing parts of Fig. 2 in another position. Fig. 4 is a horizontal' sectonal view through a fragment of the wlnd'owlstrncture and through my improved mechanism. Fig. 5 is a fragmentary elevational view of part of the driving mechanism.

Fig. 6 is a perspective view of the pinion member. l

Referring to the drawings, 1 represents a Specification of Letters Patent.

Serial No. 196,330.

Window casing or frame, such as an automobile door or the like, in which is vertically slidable in suitable guides 10 the glass wiridow pane or window member 2. In the low'er portion of the frame 1 is the pocket 3 formed between the side members 1L of the window frame, the bottom 4, the outside wall `5 and the inside wall 6, which latter is joined at its upper end to the transverse member 8 upon whose upper edge is the sill 9. The sill i) is spaced from the outside wall member 5 to form a passage through which the window member 2 may be raised and lowered from and into the pocket 3. The lower edge of the window pane or member 2 is received in the metallic channel member 11, which holds it frictionally and from which it is readily removed. Secured to the channel member 11 is a plate 12 having the horizontally extending slot 13 enlarged at one end at 14 to allow insertion and removal of the headed pin 15 secured to the sprocket chain 1G driven by the sprocket wheel 17 and passing over the idler sprocket wheel 18. A plate 19 carries sprocket wheel 17 and is joined by a strap or plate 26 to the lplate 24, on which the lower sprocket 18 ias a bearing.

Secured to the sprocket wheel 17 is the gear wheel 27 having the internal gear teeth 28, with which is constantly in mesh with the pinion 29, formed upon or securedto the rotatabledand longitudinally movable shaft 30, which extends through the slot 31, which extends downwardly from the upper end of the frame member 8 to a point just below the shaft 30. The shaft 30 has the exbut which may be of any other suitable section to move longitudinally in the similarly shaped socket in the rotatable member 33, upon which is pvoted at 34 the crank member 35 ,havlng the handle 36. The outer end of the extension 32 is beveled or otherwise suitably shaped, as indicated at 37. This beveled surface 37 is in` effeet a cam surface with which is ada ted to enage one end of the pin 38 w ich may a so be beveled or have a suitable cam shape. The pin 38 is slidable transversely in the member 33, and is engaged by the eccentric or cam surface 39 on the crank member 35. The member 33 is rotatable in the stationary sleeve 40 secured to the member 8 or to any other suitable stationary part, as to the locking plate 41 by means of screws 42, the flange of the member 40 being spaced from the plate 41 by the spacer members 43.

The plate 19 has the inwardly projecting portion 19at disposed within the internal gear 27, and the member 19 forms a bearino' at 44 for the sprocket Wheel 17 and attached gear 27,'and a flange 45 serves to hold the wheel 17 against longitudinal movement, the wheel 17 being rotatable between the plate 19al and the flange 45. The locking plate 41 is secured upon the late 19, as by rivets or screws 46. The loekmg plate 41 has formed within it the notches 47, forming in effect an internal stationary gear or pinion with which the teeth of the pinion 29 are adapted to mesh, and when meshed with the internal teeth on the plate 41 the pinion 29 is held against rotation, and being simultaneously in mesh with the internal gear 27 prevents rotation of that gear and the attached sprocket wheel 17 and therefore also prevents movement of the chain 16 andthe pin 15, which therefore holds the window member 2 locked in any desired position.

In a socket or hole in the gear member 29 is disposed a spring 48, whose one end bears against the bottom of the hole and at its other end engages in the socket member 49 carried by the part 19a, the outer end of the hole or socket in the member 29 being enlarged to receive the socket member 49.

The operation is as follows:

With the parts in the positions indicated in Figs. 2 and 4, the window member 2 is locked against either upward or downward movement from the fact that the pinion 29 is in mesh with the loekingplate 41, thereby locking the sprocket wheel 17, the chain 16 and the pinion 15, plate 12 and member 2.

If it is desired to either raise or lower the the window member 2, the operator swings the crank member 35 in counter-clockwise direction, as viewed in Fi 2, upon its pivot 34 to a position indicate in Fig. 3. In so operating the member 35 the eccentric or cam 39 pushes inwardly upon the pin 38, which in turn forces the member 31 toward the left, as viewed in Fig. 2, in opposition to spring 48, withdrawing the pinion from mesh with the plate 41. The crank member 35 may now be rotated in suitable direction, thereby rotating the member 33, which in turn rotates the member 31 and the pinion 29, which latter rotates the internal gear 27 which drives the sprocket wheel 17, which in turn drives the chain 1G, causing the pin 15 to move the plate 12 and the attached window member 2 either upwardly or downwardly, according to the direction of rotation of the crank member 35.

When the window member 2 has been moved tothe desired position, the crank member 35 is returned to the position shown in Fig. 2, and as a result of such movement the spring 48 in expanding moves the pinion 29 toward the right, Fig. 2, bringin it again l into mesh with the plate 41 an thereby locking the window member 2 in its new posltion. i

By the above described structure neither the crank member 35 nor the rotatable member 33 moves longitudinally for the purpose of lookin or unlocking the driving mecha nism. It 1s the movement of the crank member 35 uponits pivot 34 which effects the locking or unlocking of the pinion 29 with the locking plate 41.

This application is in part a continuation of my prior application Serial Number 184,476, filed August 4, 1917.
